I am trying to do a modeling\/simulation which is about a thermal analysis in a DED (laser + hot wire) metal additive manufacturing. For that I am using ANSYS built DED Process in a workbench . for the simulation I was able to create a G-code and to set the tool path for the printer in the simulation but I have some question regarding the simulation.<\/p>\n

question1: Regarding the simulation, In the real experiment, we are changing the parameter like (laser power) but i didn’t see any laser power input option in the DED wizard, it just ask me the wire feed speed and process temperature. So my question how can I account for the different parameter in the simulation?<\/p>\n

Question 2: I am having trouble with element clusttering. How do I know that how much clustter volume do I need to set? I was trying different value and ANSYS grabs volume very randomly when I set to specific value. I mean Is there any way that I can create cluster in certain nodes from certain section?how can I do that? I already got the G-Code.<\/p>\n

question3: I want to get a nice graph that could show me the top to bottom temperature profile which I can compare with Experimental data. (simulation and Experimental comparison) how can create that line to obtain a graph?<\/p>\n

For other BC like radition and convection, Do I have set it to a tabular data or step applied? All i got is the value of emissivity and convection coefficient? <\/p>\n

let me know if I am missing any other BC because this is my first attempt,<\/p>\n
